Tourna Ballport Tennis Teaching Dolly Cart The 200 ball Deluxe Dolly Cart is modeled after a dolly used by delivery drivers. The innovative design allows you to maneuver the cart very easily. Large rear wheels enable you to kick back the dolly and maneuver 200 balls up and down steps, over curbs, grass, or gravel with ease. The basket lifts off the hooks and the entire unit breaks down into 3 pieces so it can fit in the trunk of a car. Added 3rd wheel in the front makes it easy to roll around and adjust on the court while feeding balls. Lightweight steel tubing wont break your back while travelling with the cart
